"They guaranteed to me that it'll be fine, that it's nothing that's going to keep popping up," said McPherson, who underwent an MRI Friday night.
The rookie said the inflammation was affecting his play afield and at the plate.
"I was having to wrap it up and guard it," he said. "There were some things I couldn't do that I normally can do."
McPherson had been playing through the pain until Thursday, when he said the problem became steadily worse as the game progressed. For now, the plan is simply to rest and let the hip "quiet down," said manager Mike Scioscia, who added that McPherson's injuries this season were likely related.
"If the area is maybe a weak link, then it's going to affect other areas that have to pick up the slack," Scioscia said. "It looks like something if they get a hold of they can maintain and keep it at a level so he can go out there and perform."
As for McPherson, he believes he can avoid these injuries in coming years by changing his workout regimen.
"I stretch a lot now, but I need to do more of that," he said. "It seems like a lot of my problems this year have come from being a little too bulky and not flexible enough."
McPherson, who doesn't use supplements and still weighs in at a solid 230 pounds, said with a smile that he might need to try yoga.
"I can just imagine me going into that class and them trying to bend me around," he said. "I might get kicked out of class."
Sorensen back in the bigs:
Replacing McPherson on the 25-man roster Saturday was 28-year-old utilityman Zach Sorensen.
Sorensen, a switch-hitter who can play every position except catcher and pitcher, batted .322 with one home run and 28 RBIs in 48 games for Triple-A Salt Lake. He spent 122 days with the Indians in 2003, going 5-for-37 (.135) with one home run in 36 games.
"He's a plus runner, he's got a great knack for bunting, he's got a great feel for the game," Scioscia said. "He's a guy who's worked a long time to make the Major Leagues."
Sorensen said he was told to focus on the left side of the infield during his workouts, which is fine by him. In his eighth pro season, Sorensen is just happy to have another chance to contribute at the Major League level.
"This is where we all want to be," Sorensen said. "It's your goal, your dream and what you live for in baseball."
To clear a spot on the 40-man roster for Sorenson, infielder David Matranga was designated for assignment.
Matranga, 28, was 0-for-1 for the Angels in a May callup and was batting .231 with three homers and 19 RBIs in 51 games for Salt Lake.
Reversing the trend:
Outfielder Jeff DaVanon was 3-for-3 with a walk and his first home run since Aug. 25, 2004, on Friday, a feat made more impressive by the fact that the damage was done at the right side of the plate.
The switch-hitter was batting 10-for-17 (.588) against left-handers through Friday with five walks and only three strikeouts, a marked improvement from last year. In 2004, DaVanon was 3-for-22 (.136) against southpaws.
"This is really a great story, how hard he's worked on his right-handed swing," Scioscia said. "He's been squaring the ball up against lefties."
DaVanon didn't want to read too much into his performance Friday, least of all the rare roundtripper.
"I don't think [about] that," he said. "My job is to get on base and help the other guys hit home runs."
Donnelly available again:
Having completed his eight-day suspension Friday, reliever Brendan Donnelly was available to pitch Saturday for the first time this month. The Angels will stick with a 12-man staff through Sunday.
"We'll be at 12 pitchers for today and tomorrow and we'll assess some things and see where we're gonna be at after the break," Scioscia said. "We've used a lot of pitching the last couple days."
Ervin Santana (3-3, 5.50 ERA) will start for the Angels against the Mariners' Gil Meche (8-6, 4.97 ERA) at 1:05 p.m. PT Sunday in the Halos' final contest before the All-Star break.
